1 answer:
Answer:
c. natural force or pull toward the earth
Explanation:
Gravity of the earth is the force of attraction that it naturally possesses to attract any mass.
An apple falls on the earth due to this force of gravity.
The force of gravity near to the surface of the earth is given as:
where:
m= mass of the body
g= acceleration due to gravity
The variation of the gravitational force with height is given as:
where:
where
R = radius of the earth

Answer:
83.055 m
Explanation:
According to the given scenario, the calculation of skid distance is shown below:-
Where
u = 11.3
v = 0
t = 14.7
Now placing these values to the above formula,
So,
= 83.055 m
Therefore for computing the skid distance we simply applied the above formula i.e by considering the all items given in the question
Answer:
a) 316880878140.2895 Joules
b) 1056.26 Joules
c) 372.80103310622 km²
Explanation:
Energy consumption
Average rate of electrical energy consumption is 316880878140.2895 Joules
Total population = 300 million
Each person consumes 1056.26 Joules.
Efficiency = 0.85
Power from Sun
Area
Converting to km²
Area required to collect the electrical energy used in the United States is 372.80103310622 km²
